DELIVERING LIQUIDS IN MEASIlRED'QUANTITIES BY VOLUME Application filed July 1, 1926, Siirial No.'119,857, and in Great Britain January 25, 1926.

This invention relates to improved apparatus for delivering liquids in measure quantities by volume, and is specially 'apph-' cable to measuring apparatus for use in ga- 5 rages and the like to supply measured quan-. tities of petrol, and theobject is to provlde an apparatus adapted to measure desired quantities accurately and expeditiously, and

in the useof which the operations of filling the measuring compartments to the required level and emptying them can be observed throughout by the purchaser. 1

According to the invention the apparatus comprises a rotatable measuring vessel having a measuring compartment, or several such compartments adapted respectively to measure different volumes, the measuring vessel .being so mounted, in relation to a spout to which the liquid to be measured is supplied by suitable control means, and in relation to a delivery pipe, that the vessel can be turned from a position in which a come partment is adapted to be filled by the s ut,

to aposition in which the contents 0 the said compartment are discharged to the delivery pipe. The vertical side or sides of -the measuring vessel are preferably made of a transparent material, or are fitted with.

windows, so a ranged that the operation of 8c filling the compartment, the level to which the compartment is filled and the operation of emptying the compartment, are visible. The respective measuring compartments are preferably fitted with an overflow opening. at a levelcorrespondingwith the'volume'to be measured, and the measuring compartment is mounted in a casing so arranged that the liquid is discharged to the delivery out-- let. whereby the filling of the compartment withthe desired volume is ensured, by supplying an excess of liquid to the compartment which excess passes through the overflow opening. I

Usuallythere are four compartments, two, of them each having a capacity equal to the most frequently employed unit, say a gallon, and these compartments are arranged diametrally opposite so that as the one is emptied the other may filled. When the I L liquid reaches the desired level in any com-.

partment any surplus overflows and returns d to the store tank.

Each of the compartments of the measuring vessel is preferably fitted with a fill-pipe provided with overflow outlets, which pipe is brought under the supply spout in the act of filling, and the transverse cross-sectional area of which is considerably less than that of the portion of the measuring compartment with which it communicates,

In the preferred arrangement the measuring vessel takes the form of a frustum of a cone with transparent ends, and is mounted on a horizontal axis in a container also have ing transparent ends; the vessel is divided into measuring compartments of different capacities by radial partitions, and each compartment is provided with a. fill-pipe, the compartment which 'is' being filled being turned into the upper position with its fill- 79 pipe below the supply spout, the overflow from the-fill-pipe being led to the rear part of the outer casing and being returned to the store tank; when it is desired to empty the compartment it is turned through 180 de- -giees and discharges its contents through the l-pipe to a sump in the front part ofthe containerto which any suitable form of delivery pipe is fitted.

The filling of the effected by connecting the supply spout through a suitable'control valve to a supply of liquid having the "necessary head, or where the liquid is below the apparatus, the

supply spout may befed by-means of a pump I or by displacing-the liquid in the tank, or by subjecting the liquid to the necessary pressure; usually a pump is employed which may be set to give slightly more than the quantity of. liquid necessary to fill the respective compartments, and the means by which the quantity delivered by the pump is varied to suit the different compartments may be controlled by the movement of the rotatable measuring vessel, so that the pump is set to deliver the quantitycorresponding with the vessel then being filled.

The invention also comprises improvements in connection with the delivery pipe supplying the vessel; the overflow arrangecompartments may 'be I wheel and cam plate;

ments; locking arrangements to prevent discharge until the desired level of liquid corresponding with the required measure has been reached; and other details of construction, all as hereinafter described and claimed.

The invention is illustrated in the accompanying drawings, in which Figs. 1 to 3 illustrate, more or less diagrammatically, the arrangement when the axis of the'measuring vessel is horizontal.

Referring first to Figs. -1 to 3 A is a fixed casing'having a front window a and a rear window a which casing is mounted on any suitablesupporting structure, such as the columns C, at a height sufficient to enable the liquid to be delivered by gravity from the sump a through the discharge pipe a, to the tanks of, for instance, motor vehicles.

B is a rotating measuring vessel which in shape is preferably a frustum of a cone, having a front transparent window 6 and a rear transparent window 6 the vessel B is mounted on the axis 6 supported in suitable journals in the casing A, and is rotatable by any suitable means such'as bevel wheels 6 and actuating shaft 6 The measuring vessel is divided by radial partitions b into four compartments; the two larger and diametrically opposite compartments may conveniently'be adapted to measure the unit employed when supplying a quantity of liquid, for instance, several gal- Ions, the small compartments measuring different fractions of a gallon. Each compartment is fitted with a fill-pipe I) having overflow notches b so arranged that when the level of liquid in the fill-pipe corresponds with the notches, the compartment contains the desired volume to be measured; the liquid which overflows through the overflow notches b is led back to the store tank in any convenient manner.

In the example. illustrated overflow wells 6 are provided which surround the respective fill-pipes and into which the liquid which overflows passes, andfrom which 'the said liquid is led by respective overflow pipes 6 to the rear end of the casing'A, from which it passes through a suitable pipe a and is returned to the store tank. v

D is the supply pipe to which the liquidto be measured is supplied by any convenient means, say under a suitable head, the

flow being controlled by any suitable device such as a cockor valve indicated at When a particular measure is required the corresponding compartment is moved to the position in which its fill-pipe is below the supply pipe, and liquid is supplied until it begins to overflow through the notches b; as the cross-sectional area at the liquid level is then comparatively small, being that of the fill-pipe b", the capacity can accurately be calibrated; the filling. of the compartment and the of the liquid to the desired level can be observed by the purchaser through the window 6 the said-window also forming the front of the fill-pipe as .shown. When the uppermost compartment has been filled it is rotated through 180 degrees, whereupon the contents are discharged through the fill-pipe b into a sump a which if desiredments would have indicated thereon the ca pacity of the respective compartments. a.

Where, for instance, several gallons of' liquid have to be supplied, the two oppositely located one-gallon com artments are alternatively brought to the lling position, the

one compartment emptying as the other is being filled, thus materially reducing the time required to measure the given quantity.

Where the axis of the measuring vesselis vertical, the arrangement takes the form lustrated in Figs. 4to 6, in which A is the fixed casing, and B the rotating measuring vessel; the measuring vessel B is carriedby a suitable shaft 6 mounted in suitable bearings formed, tor-instance, by a ball racea carriedfrom a central boss a formed inthe interior. of the container A the upper end of the axis being carried by a bearing a formed in the cover a, and the lower end beingsteadied by a bearing a formed in the base plate a" by which the containing vessel A is carried by columns such as a, which in turn are supported by a suitable stand or base a.

The measuring vessel is divided by vertical partitions 6'" into two one-gallon compart ments oppositely located, and intermediate compartments having capacities corresponding with fractions of a gallon.

As'before each compartment is provided with a fill-pipe 6 having overflow notches 6 the top of each compartment with the exception of the fill-pipe being closed by a a conical cover I) having an-extending ledge b reaching nearly to the interior of the container A so that the liquid overflowing through the notches 6 is shed by the cover and is discharged into the part a of the outer container, from which it drains through the pipe a to the store tank; the part a of the container A is divided from the part a bythe radially disposed partition a which extends to a suitable height radially across the vessel. The part a 'is fitted with a discharge pipe a 1 Each compartment is at its lower end provided witha valve 72 which is normally closed, but the stem 6" of this valve, when.

the respective compartments come opposite the discharge pipe'a, engages with a cam plate a made in bracket form and supported from the interior of the casing A. Engage- -ment of the stem 15" with the cam a ralses the valve so that the contents of the compartment are then discharged into the part a of Y the container A, and thence by the discharge pipe a to any desired receptacle.

Each compartment is fitted with a glazed front 6 which also extends over the front portion of the fill-pipe, and each compartment has an air vent b, the top of which is carried to or above the height of the overflow notches b i D is the supply pipe, which in the exampleillustrated is fitted with an air vessel d having a ventpipe d, the lower end of which opens into the interior of the vesel A, and

the upper end of which opens into the upper end of the air vessel P; the object of the air vessel is to prevent too sudden a flow of liquid from the supply pipe I) to the fill-pipe.

The pipe D may be supplied withthe liquid to be measured in any convenient manner; in the example illustrated the pipe D is connected to the interior of one of thecol umns a which in turn is connected through a suitable control valve to a store tank which may be below the apparatus, and from which 4 Where, as hereinafter described, a variable- 1 stroke pump is used to deliver the liquid to be measured to the pipe D and it is desired that the pump shall deliver quantities corresponding with the capacities of the measuring compartments then under the supply pipe, the wheel E may be fitted with a cam which in the manner hereinafter described operates means which limit the stroke of the pump according to the angular position of the wheel E and therefore of the measuring vessel B The containerA may be constructed ontirely of glass as in the example illustrated,.

or, of course, it may be of metal with glass windows."

' It will be seen that the operations of filling a compartment to the desired level and of emptying it through the pipe a can be closely observed by the purchaser, and-that the volume delivered, providing the compartment is filled to the level of the overflow notches, is i quite independent of the initial height of the l1qu1d in the pipe D Where the pipe D is supplied by means of the variablestroke pump, the liquid delivered by the pump to supply the respective compartments would be arranged to be slightly in excess of the quantity required to fill the compartment to the desired level, so as to eliminate errors due to leakage and the like, the surplus returning to the store tank through the overflows.

Referring now to Figs. 7 to 31, which illustrate the preferred arrangement so constructed as' to be adapted to be applied to exlsting liquidmeasuring devices comprising a variable-stroke pump drawing its supply from a store tank containing liquid to be delivered,--

A is the outer casing'which is carried from the upper end of a column 0 in turn carried by a gear box 0 supported from the pedestal C, the latter being supplied with a suitable foot by which it is attached to a suitable foundat1on;'the arrangement of the pedestal C and box 0? fitted with doors is that commonly employed in connection with the variable-stroke pump measuring devices, the

pump P being enclosed in tne pedestal C, and the gear for operating it beingenclosed 1n the box 0 The pump which may be of the ordinary suction lift type is operated by a rack 9 pinion p and handle 12 (see Fig. 11) the shaft 12 of which is geared by intermediate gearing p to the pinion shaft 1).

The pump delivers the liquid to a supply pipe al which pipe (see Fig. 18 which is a rear view and shows the pipe (1, on the righthand side) is connected by a suitable union (1 to an annular space between the inner and outer walls a and a of the cylindrical portion of the casing A. The liquid supplied rises in the said afinular space and passes to the supply spout, D. This spout makes joint with the inner wall a and extends into a spigot (Z carried from the outer wall a; the portionof the wall (1 between the supply spout D and the spigot (I? being perforated as shown at (Z in Figs. 28. and 29, and the spigot (Z13 being fitted withan air-vessel d, which air vessel is fitted with a ventpipe (Z carried through the walls a and a, its lower end opening into the interior of the casing A, and its upper end being carried to the upper end of the air vessel d. The liquid supplied to the annular space rises through the perforations (1 part of the liquid passing down through the spout D and part passing into the air vessel d.

The object of the air' vessel is to prevent too sudden a rush of liquid through the spout D. The liquid passing into the air vessel (1 ultimately is delivered through the spout D, the level of liquid,-after a filling operation should there be no leakage at the pump, remaining at or about the level of the top of the supply spout D. The front and back of the casing A are closed by glass windows a and a which are jointed to the walls of the casing in any suitable manner; for instance, by forming flanges-a and .is not carried right round the casing, but is stopped-off on each side of the outlet (1 as shown.

The interor of the casing is fitted with a transverse partition plate a, the outleta being on the front side of this partition, and a second out-let a being formed at the bottom of the wall a, the latter outlet being connected by a union (1 and pipe 0. leading to the store tank. The unions a and d pass in fluid-tight manner through the sump F. The sump F is fitted with an outlet pipe 1 to which a hose pipe f and nozzle i may be fitted, by which the liquid delivered to the sump is conveyed to any desired receptacle.

The casing A is fitted with a rotating measuring vessel B, theconstruction of which will be understood by reference to Figs. 14 to 17 A.

equal oppositely located compartments being designed to measure one gallon, and the m-' termediat'e compartments to measure respectively half-gallons and quarts. Each compartment is fitted with a fill-pipe b the bottoms of the fill-pipes making oint with suitable openings formedin the wall 5 so that the interiors of the fill-pipes communicate with the respective interiors of the measuring compartments. Each fill-pipe is provided with overflow notches 12 and around each fill-pipe is provided an annular overflow Well or sump 6 formed by the circular wall I), the lower edge of which makes joint with the wall I) of the casing, and each well is provided with an outlet pipe I). The front portion of the fill-pipe and the front portion of the wall 6 are cut away as shown in Figs. 15 and 26, the respective cut edges lying in the same transverse plane as the front circular edge of the wall I) and the front edges of the partitions b==,so that the inner face of a. glass window b" makes joint with these respective edges. 7

The joints b tween the inner faces of the glass windows 6 and I), and the edges of the wall I) and the partitions b", are made as shown in Fig. 27; tie rods 7)?" are securedto the plate b and the glass windows are drilled to take the screw-threaded ends of therods, the joint being made by tightening the nuts fitting the rods. 7 The edges of the plate I; and the partitions b" are fitted with grooved strips b the joint being made between the glass and a packing b tted in the groove.

The joints between the edges of the walls 6' of the well and the edges of the fill pipe b? are fitted with grooved strips b fitted with packing'bf and the joint is made by the tie rods 12 which pass around the wall 13 as which is held in place by the end nuts I);

bearings for the spindle b are formed by screwed sleeves b and b" secured respectively in central holes formed in the front and rear glass windows a and a, of. the eontainer A, which sleeves are held in positions by nuts. 6 7

The measuring vessel is mounted in the container as shown in Figs. 7 and 8, and onthe rear protrudin end of the spindle 6 a chain wheel 6 is 'xed, the chain wheel, the spindle, the tube 6 and the'measuring vessel rotating together. The chain wheel 6 (see Fig. 9) is geared by a chain b to a chain wheel 12 on a sleeve b carried by a stud b" on whichsleeveis mounted a second chain wheel 6 on one side of the chain 6 (which passes round the guide pulley 12) to the chain wheel 5 which is secured to a hand wheel E loosely mounted on the shaft 12 the gearing being so arranged that the hand wheel'E I and the measuring compartment B have ual angular velocities. I The hand wheel E is provided with four studs 6 on which are'respectively engraved the measuring capacities of the respective measuring compartments into which the measuring vessel B is divided, and the gearing is so arranged that when the stud corresponding to a particular measure is moved to its uppermost position, as shown in Fig, 9,. the'corresponding compartment has its fillpipe 12" brought under the supply pipe D.

Where, as in the modification now described the measuring compartments are filled through the action of a pump, the appropriate stroke of the pump for the particular compartment then being filled is ensured by operating a vertical shaft G (see Figs. 7 and 10) through a cam surface formed 'in' the interior of the rim of thewheel E, so as to impart the angular movement to the shaft G necessary to bring into the path of movement of a stop piece p, fixed to the rack 12, the appropriate limit stop 9? or 9 the limit stop 9 m the example illustrated, arresting the movement of thepumpbucket when'the compartment measuring aqua-rt is below the delivery spout D; and the limitstop g limiting the stroke of the pumtpuwhen the half gallon compartment is being ed, both limit stops 9 and. 9 being moved clear of the stop piece 12' when either of l the one-gallon compartments has to be filled, the movement of the stoppiece 'p" being then arrested when it engages with the underside of the main casing a or other suitable fixed point'.. a

The arran ement for mpartlng movement to the shaft compr1ses a cam surface e (see Figs. 21 to 25) which is formed on the inside of the rim of. the wheel E, said cam surface having a depression e and aprojection e adapted to engage with the roller g of the cam lever g, keyed to the shaft G which latter is fitted with a spring 9 (see Fig. 10)

which tends to keep the cam roller 9 in contact with'the'cam surface.

When the roller is in contact with the depression e the limit stop 9 is inter osed in the path of the stop piece 12' (see when the cam rbller is in contact with the projection e the limit stop 9? is interposed in the path of the stop piece 12'' (see Fig. 25) when the cam roller is in contact with the in-' termediate surface a both limit levers g and g are clear of the piece p" (see Fig. 12). :VVhen a articular measuring compartment is being fied, the wheel 'E is, as soon as the rack 12 commences to move upwardly, locked by a rod H, the lower end of which is carried in the foot-step bracket 72 a spring if being interposed between the lower end of the rod and the bottom of the bore of the bracket, which spring tends normally to move the rod H upwardly. Upward movement of the rod in the non-locking position is prevented by a lever hi the end of which engages the underside of the stop piece 1) when the latter is in its lowest position, the lever it having a forked end h which embraces the part p fof the pump rod to which the rack 12 and the stop piece 11' are attached; when the stop piece 72 moves up as the pump is operated, the lever b is released and the rod H is moved upwardly by the spring 71. the upper end h of the rod H, which is guided by the bracket h, then engaging with the appropriate hole a in the rim of the wheel E, thus locking this-wheel and the measuring vessel geared to it in the arm 7: clear of the locking piece '5 appropriate filling position. This lock is not removed until the return stroke of the pump is completed by the reverse movement of the handle 11 when the stop piece 12' again engages the lever h This provides a sufficiently long time interval after the operation of the pump to ensure that the whole of the 1iquid delivered by. the pump shall be delivered to the fill-pipe of the compartment then being filled, thus preventing the vendor from moving, by the operation of the Wheel E, a compartment from its filling position to its discharging position until it has been filled to the requislte level.

Where it is desired to provide an independent locking device to prevent the measuring vessel being moved from its filling position until the compartment then being filled is full, the device illustrated in Figs. 30 and 31 isfitted. Each compartment is provided with a float I slidable on a float rod 5 the lower end of which is guided by a foot-step bracket 5 and the upper end of Which'is attached to the arm 2' of a double armed lever fulcrumed at i on the bracket i the other arm a of which lever is adapted, when the float is intermediate stop pieces 2' and i fixed on the float rod 5 to be brought by the spring i into engagement with a fixed slotted locking piece i carried by the containing vessel A.

When the compartment is empty the weight of the float I on the lower stop 17 raises the The float of'the compartment which is below the delivery pipe will, as soon as the compartment begins to fill, be supported by the liquid therein and will rise clear of the stop 71', thus allowing the spring 2' to pull the lever i into engagement with the stop 2' and so prevent movement of the measuring vessel until the vessel is filled to the level of the overflow, when the upward pressure of the float I on the stop 2' raises the arm a and depresses the arm 71 so as to move the latter clear of the stop z'fl'whereupon the measuring vessel can be rotated to move the compartment then filled from its filling to its discharging position.

The action is as follows Assuming that a half-gallon of liquid has to be measured ;the wheeLE is rotated until the stud bearing the words half-gallon is moved to the top position, this brings the fill-pipe of the half-gallon measuring compartment below the supply spout, and brings the limit stop g in line with the stop piece 12'. The pump is then operated by the handle this raises the locking piece 72', whereupon the lever 72, is freed, and the locking rod H engages with the appropriate hole in the wheel E, thus locking the wheel E and measuring vessel.

The pump is operated until the locking piece p7 engages with the limit stop 9 and this stop is preferably so located on the rod G that slightly more than half a gallon of liquid is delivered by the pump.

Assuming that the level of the liquid, after the previous measuring operation, coincided with the top of the delivery spout, it will be seen that the pump action will ultimately deliver through the delivery spout to the fillpipe slightly more than half a gallon; the surplus will overflow through the-overflow notches 1) into the sump b and thence through the outet pipe Z), the surplus liquid flowing to the interior of the container in rear of the partition plate a, and finding its way through the outlet a, union a and pipe (1 back to the store tank.

This operation will have been completed by the time the return stroke of the pump is made and the wheel E unlocked. Should, however, for any reason, the liquid level in the half gallon compartment not be raised to the overflow level, the operation of the float I will prevent movement of the measur- V ing-vessel. Assuming however that the desired level has been reached, the measuring vessel is then turned through 180 degrees by the operation of the wheel E, whereupon the contents of the vessel will be discharged through the outlet a into the sump F and thence by the outlet pipe 7, the hose pipe f and nozzle fto the desired receptacle.

It will be observed that by the provision of the glazed end window, the operation of filling the compartment can be observed bythe intending purchaser, and that by follow ing the movement of the measuring vessel from the filling to the discharge position he can be satisfied that the correct quantity of .liquid as measured, is delivered through the hose pipe i It will further be seen that whilst there is no necessity for-using a pump in conjuction with a measuring vessel, a pump the stroke of which is controlled in accordance with the movement of the measuring vessel, forms a convenient adjunct to the apparatus, with a further advantage that the invention can be applied with comparatively little alteration, to the variable stroke pump delivering devices now in general use.

It will further be seen that where a specified number of gallons of liquid have to be delivered, the fact that the two one-gallon compartments are diametrally opposite, permits the use of the apparatus in such manner as to bring these two compartments albernately under the supply spout, the one compartment emptying at the same time the other is filling, thus reducing'the time-re quired to measure a given number of gallons.

The arrangement of a rod such as G and limit stops such as g and g whereby the stroke of the pump can be varied so as to deliver a given quantity of liquid is well known in connection with pumps of this type.

It will be seen however that unless the liquid in the delivery pipe ismaintained, be-

tween successive menu-mi operations, at the overflow level in the stan pipe, the portion of the measured quantity of'liquid delivered by the pump will,in the ordinary type of vanablestroke pum measur' devices, be used tofill the stan pipe to the said level, and will be lost tothe purchaser. The addition of the measuring apparatus described however, prevents this possibility of loss to the purchaser.

The arrangement illustrated in Figs. 32

' and 33 is substantially similar to that described, except that the fixed outer casing A may be made mainl of metal, the front window a being fitt in a suitable recess a, the rear windows a .being of sector-shape and beingt'fitted in suitable recesses formed between t e arms a. In this case the cylindrical portion neednot be constructed withan annular space between inner and outer walls, the supply pipe I) being led directly to the air vessel and supply spout D. p

In order to obviate the necessity to form a bea a spin e a" having a flange a and nut a may be secured in position in ahole in the centre of the rear end, the tube 6 passing through the centre of the vessel 13", being to tatably mounted on the fixed spindle a.

This construction permits of the chain- 1. In apparatus for delivering liquids in measured quantities by volume in combination;--a fixed casing having alglazed front;
